FIG. 9 provides a graphic illustration and brief summary of the pinlayout that is accessible through the interface surface 40 shown in FIG.5 . In the embodiment shown, the battery pin layout includes three highcurrent pins and twelve low current pins. The high current pins are usedto supply electric power from the battery while the low current pins areused to relay information from the battery controller and receiveinformation signals that are relayed to the battery controller fromother components on the lawn tractor/ZTR mower. The information istypically related either to the battery operation or operation of theoutdoor power equipment. The high current pins are separated andshielded from the low current pins and from each other. Although oneconfiguration in shown, it should be understood that a different numberof pins could be utilized while operating within the scope of thepresent disclosure.

In the embodiment shown in FIG. 9 , pin 52 is a twelve-volt high currentstarter pin that is connected to the starter motor, such as through theline 26 shown in FIG. 2 . The controller 18 shown in FIG. 2 selectivelyapplies the voltage and current from the high current pin 52 to thestarter motor 10 when desired to start the internal combustion engine12. High current pin 54 is a conventional ground pin that is connectedto the chassis or the engine. The final high current pin is atwelve-volt auxiliary output/charging input pin 56. The twelve-voltauxiliary output/charging input pin 56 is connected to the alternatorsuch that the alternator can recharge the electric starter batteryduring operation of the internal combustion engine. When the internalcombustion engine is not operating, pin 56 provides twenty amp auxiliarypower to the electric components on the tractor/mower, such asheadlights, a radio or other electrical components.

The battery pack includes a series of low current pins that are groupedin the low current interface area 57. The first low current pin is anenable pin 58 that is connected to the key switch of the outdoor powerequipment. Through this enable pin 58, the battery controller locatedwithin the electric starter battery 24 can determine whether the keyswitch is in the auxiliary position. When in this position, the battery24 will supply electric power to the auxiliary devices when the internalcombustion engine is not running. During operation, electric power issupply to these auxiliary devices from the alternator.

The next pin is the starter enable pin 60 that is connected in line withthe PTO and clutch. The starter enable pin 60 is inline with the PTO andclutch and receives an input from the key switch to enable starting ofthe internal combustion engine.

The remainingpins shown in FIG. 9 can be used for additional enhancements in thefuture, including enhanced communication, identification of the batteryand programming.

FIG. 10 illustrates a first possible application for the electricstarter battery 24. In the embodiment shown, the electric starterbattery 24 is received within a receptacle 80 that is mounted to theinternal combustion engine 12 of a lawn tractor 84 near the startermotor. The mounting of the receptacle 80 to the engine creates veryclose positioning between the starter battery 24 and the starter motor.Such location will reduce the amount of copper wiring needed between thestarter battery and the starter motor, thereby reducing both materialcosts and assembly costs. When mounted in this location, the electricstarter battery 24 will be concealed beneath the hood 82 of the tractor84 during operation of the tractor. The position shown in FIG. 10 placesthe battery 24 under the plenum, which directs outside air onto theengine and will thus cool the starter battery 24.

FIG. 11 illustrates the same electric starter battery 24 mounted to theinternal combustion engine 12 of a ZTR mower 86. The electric starterbattery 24 includes the similar receptacle 80 and the combination of thereceptacle and electric starter battery are located near the startermotor of the ZTR mower 86. In this embodiment, the electric starterbattery 24 will be viewable to the user during operation, which may bebeneficial to monitor the state of charge on the starter batter 24.

FIG. 12 illustrates the electric starter battery 24 mounted to anothertype of outdoor power equipment, namely a snowthrower 88. In theembodiment shown, the starter battery 24 is mounted to the engine of thesnowthrower 88 utilizing the same receptacle 80 described in FIGS. 10and 11 . The receptacle 80 is located near and electrically connected tothe starter motor of the snowthrower 88 and in a location where thestarter battery 24 can be viewed and easily accessed.

FIG. 13 illustrates the electric starter battery 24 mounted beneath thesteering column 90 of the lawn tractor 84. In the embodiment shown inFIG. 13 , the receptacle 92 is slightly modified from the pastembodiments. The receptacle 92 performs the same functions as thereceptacles described previously, namely providing a secure receivinglocation and connecting the starter battery 24 to the starter motor. Arelease button 94 allows for the easy removal of the electric storagebattery 24 for charging or other replacement.

FIG. 14 illustrates yet another contemplated mounting arrangement forthe electric starter battery 24 on the internal combustion engine 12. Inthe embodiment shown, the receptacle 96 is designed to integrate withand receive the oil dipstick 98. The receptacle 96 is modified from thepast embodiments to include a dipstick receiving tube 100 that includesa lower end 102 received on the conventional access opening 103 on theinternal combustion engine. The access opening 103 provides access to anoil sump of the internal combustion engine in a known manner. Thedipstick receiving tube 100 is molded with the battery receiving portion105 which is design to receive the battery 24 in the same manner as thereceptacles described above. The dipstick receiving tube 100 includes aninternal opening that guides the dipstick 98 into the oil sump such thatthe level of oil in the oil sump can be determined.

The battery receiving portion 105 includes a release button 104 thatallows the operator to release the electric starter battery 24 forremoval as desired. In the embodiment shown in FIG. 14 , the lower end102 of the dipstick receiving tube 100 could include an oil level sensorthat would be positioned to sense the oil level in the oil sump. The oillevel sensor would operate to relay information to the controllercontained within the electric starter battery related to the sensedlevel of oil. The controller in the starter battery could then relay thesensed oil level to a wireless device, such as a smartphone, which canprovide real time alerts to the operator when the oil level falls belowa minimum level. The receptacle 96 includes a strap 106 surrounding thestarter motor 10 to help hold the receptacle 96 on the engine andstarter motor 10.

FIG. 15 illustrates the electric starter battery 24 being removed fromthe battery receiving portion 105 of the receptacle 96. As can be seenin FIG. 15 , the receptacle 96 includes the various high currentcontactors and low current pins that engage with the battery pin layoutdiscussed previously. Since the electric starter battery 24 can beeasily removed and inserted into the receptacle 96, the entire battery24 could function as a “key” to enable operation of the lawntractor/mower. In such an embodiment, when the battery 24 is insertedinto the receptacle 96, the insertion would “enable” operation of a pushbutton starting device or ignition key switch, depending on theconfiguration of the outdoor power equipment. If the battery 24 is notpresent within the receptacle 96, the engine cannot start and would thusbe disabled. In this manner, the battery 24 would function as a key forthe tractor/mower. The size and shape of the battery 24 could bemodified in such an embodiment to make removal easier and moredesirable.

FIG. 16 illustrates one contemplated method of charging the electricstarter battery 24. As described previously, during normal operation ofthe outdoor power equipment, the alternator on the equipment wouldcharge the starter battery 24. However, if the starter battery chargebecomes depleted for whatever reason, it may be necessary to rechargethe battery at a location removed from the equipment. In thisembodiment, a wall mounted outlet 108 receives the charging plug 110which is connected by cord 112 to the low voltage interface plug 114.The low voltage interface plug 114 includes a series of aligned contacts116 that are received within the series of low current contact pinsformed within the interface surface 40. Display 36 allows the user todetermine the charge status when the battery 24 is being charged in themanner shown in FIG. 16 .

FIG. 17 illustrates yet another way to charge the electric storagebattery from an external power source while the battery is still mountedon the mower. In the embodiment shown in FIG. 17 , a charging plug 118can be uncovered and connected to the wall outlet through a similar cord112 and plug 110. In the embodiment shown in FIG. 17 , a femalereceptacle 120 receives the plug 118. The embodiment shown in FIG. 17would allow the electric storage battery 24 to be recharged when theelectric storage battery remains mounted on the mower. Such situationmay be required if the electric starter battery is used to operateauxiliary equipment on the mower without starting the mower, which wouldresult in complete discharge of the electric starter battery.

FIG. 18 illustrates additional enhancements made possible utilizing theelectric starter battery 24 of the present disclosure. In the embodimentshown in FIG. 18 , the circuit board 32 (FIG. 6 ) contained within theouter housing is designed to include the battery controller and awireless communication transceiver. The wireless transceiver cantransmit wireless signals from the battery controller utilizing knownwireless communication techniques, such as Bluetooth 122. When a userdepresses the sync button 39, the wireless transceiver sends out aBluetooth signal that can be received by an external wireless device124, such as a smartphone. Once the battery controller of the starterbattery 24 and the wireless device 124 have been synched together in awell known manner, communication can occur between the two devices.Since the wireless device 124 can communicate using telephone datachannels, the information received at the wireless device 124 can beshared to remote locations for monitoring. As an example, informationfrom the tractor/mower could be streamed in real time from the battery24 to the wireless device 124 and then to a remote location that caninclude monitoring software. This software could be at the manufactureror at the users for performance monitoring. Such performance monitoringwould be able to predict problems with the mower operation or alert theuser when some monitored parameter is out of a desired operating range.The operator can also download computer application software directlyonto the wireless device 124 to receive information from the starterbattery 24 and monitor mower/tractor performance in real time. Thewireless communication between the starter battery 24 and the wirelessdevice 124 would open a wide variety of possible communicationapplications.

The communication between the wireless device 124 and the batterycontroller of the starter battery 24 could be continuous duringoperation of the outdoor power equipment, which would allow the user tomonitor operating parameters and conditions. As shown in FIG. 19 , inone embodiment of the present disclosure, the wireless device 124 can bemounted within the center of the steering wheel 126 to provide adashboard display 128 for the user. The dashboard display 128 can beconfigured as desired by the application software on the wireless deviceand can display a wide variety of tractor/mower related information tothe operator of the tractor/mower. This information can include currentengine speed, oil temperature, a fuel gauge, oil pressure, number ofhours used, as well as other information that may be interesting oruseful for the operator. By using the wireless device 124 as thedashboard display, the cost of a dedicated display for the tractor canbe eliminated. Further, the application software on the wireless devicecan be updated by the user and the manufacturer to add additionalfeature and functions.

In the embodiment shown in FIG. 19 , a pair of gripping brackets 130 ismounted to the steering wheel to securely hold the wireless device 124in position on the steering wheel 126. The gripping brackets 130 can beformed from a flexible, resilient material that protects the wirelessdevice 124. The gripping brackets 130 can be adjusted on the steeringwheel to accommodate wireless devices 124 having different sizes andfrom different manufacturers. The wireless device 124 is positionedclose enough to the electric starter battery 24 such that the electricstarter battery 24 can relay and receive wireless signals from thewireless device 124.

FIG. 20 illustrates an alternate embodiment of the starter battery 24 inwhich the back face 42 of the starter battery 24 includes a receivingslot 132 that can receive a communication dongle 134. The dongle 134interfaces with contacts 136 to communicate with the battery controllermounted to the circuit board contained within the starter battery pack.The dongle 134 includes a wireless transceiver and thus can be used toadd wireless communication to the battery 24 if a user/operator wishesto upgrade at a date after purchase. By removing the wirelesstransceiver from within the starter battery 24, the initial purchasecost of the starter battery 24 can be reduced for some users whileallowing the user to add the communication feature if desired in thefuture.

FIG. 21 illustrates another type of dongle 138 to permit wirelesscommunication with the wireless device 124. Again, the dongle 138includes the wireless transceiver that communicates with the batterycontroller mounted on the circuit board contained within the starterbattery 24 and can be added by a user/owner at a later date shouldwireless communication become desirable.

FIG. 22 illustrates an RFID/NFC chip 140 added to the internal circuitboard within the battery 24. The RFID/NFC chip 140 is positioned behindthe back face 42 of the outer housing of the battery 24. The RFID/NFCchip can be used to identify the type of engine/equipment being used andpowered by the electric starter battery. In this manner, the controllerof the electric starter battery can configure operation of the batteryand various other applications based upon the type of engine beingstarted. As an example, a snowthrower engine may have different crankingrequirements and timing for the starter motor due to the cold weatheroperation environment as compared to a ZTR mower. If the controller ofthe battery 24 can identify the type of engine and application, thecontroller can modify the operation of the battery pack to optimizeperformance.

FIG. 23 illustrates the use of the wireless device 124 to scan a uniquecode 142 applied to the engine 12. Through this code 142, the wirelessdevice 124 can identify the type of engine and application and relaythis information to the battery controller of the starter battery 24.Upon receiving this information, the starter battery 24 can configureits operation since different features may be required depending uponthe type of application.
